Sugar as Soil Amendment: Origins & Practice

Source: Howard Garrett (The Dirt Doctor)

Texas organic guru recommends dry molasses for soil microbes. If unavailable, table sugar works—same carbon source, purer, cheaper.

Why Sugar Works

• Feeds beneficial bacteria/fungi.
• Microbial activity improves structure, nutrient cycling.
• Rich soil suppresses weeds (they prefer poor soil).
• No burn risk, pet/kid safe.

Application

1 lb sugar per 250 sq ft. Broadcast dry, water in. Spring and fall. No fancy equipment needed.

Beer, Molasses, etc.

Work because of sugar content. Why pay more for diluted sugar? Pure sucrose is most cost-effective.

Results Speak
